1. A diabetic patient's blood sugar is 180mg/dL. Their usual insulin dose is 1 unit per 40mg/dL above 100mg/dL. How much insulin should be administered?

• A. 2 units
• B. 3 units
• C. 4 units
• D. 5 units

Correct answer: B

Rationale: Rationale: 1. Calculate the excess blood sugar above 100mg/dL: 180mg/dL - 100mg/dL = 80mg/dL. 2. Determine the insulin dose based on the patient's usual insulin dose: 80mg/dL / 40mg/dL = 2 units. 3. Add the calculated insulin dose to the patient's usual insulin dose: 1 unit (usual dose) + 2 units (calculated dose) = 3 units. Therefore, the correct answer is 3 units of insulin should be administered to the diabetic patient with a blood sugar level of 180mg/dL.

2. How many moles of oxygen are required to completely react with 5 moles of propane (C3H8) in the combustion reaction?

• A. 5 moles
• B. 10 moles
• C. 15 moles
• D. 20 moles

Correct answer: b

Rationale: The balanced equation is C3H8 + 5O2 → 3CO2 + 4H2O, indicating a 5:10 ratio between moles of oxygen and moles of propane.

3. Which element is used in insulin and promotes glucose uptake into cells for energy production?

• A. Zinc
• B. Chromium
• C. Manganese
• D. Iron

Correct answer: B

Rationale: Chromium aids in insulin's function, enhancing glucose uptake by cells and regulating blood sugar levels.

4. What is the structure that connects the ovary to the uterus in the female reproductive system?

• A. Urethra
• B. Fallopian tube
• C. Vagina
• D. Cervix

Correct answer: B

Rationale: The correct answer is B: Fallopian tube. The fallopian tubes are the structures that connect the ovaries to the uterus in the female reproductive system. These tubes play a crucial role in the fertilization process by providing a pathway for the egg to travel from the ovary to the uterus. The urethra (A) is a structure that carries urine from the bladder out of the body and is not directly involved in the reproductive system. The vagina (C) is the canal that connects the external genitals to the cervix and is not the structure that connects the ovary to the uterus. The cervix (D) is the lower part of the uterus that connects to the vagina and does not connect the ovary to the uterus.

5. Which organelle is responsible for packaging and secreting proteins into the extracellular space?

• A. Golgi apparatus
• B. Mitochondria
• C. Ribosomes
• D. Endoplasmic reticulum

Correct answer: A

Rationale: Rationale: A) Golgi apparatus: The Golgi apparatus is responsible for modifying, sorting, and packaging proteins into vesicles for secretion outside the cell or for use within the cell. B) Mitochondria: Mitochondria are known as the powerhouse of the cell and are responsible for generating energy in the form of ATP through cellular respiration. They are not involved in packaging and secreting proteins. C) Ribosomes: Ribosomes are responsible for protein synthesis, where they translate mRNA into proteins. They are not involved in packaging and secreting proteins into the extracellular space. D) Endoplasmic reticulum: The endoplasmic reticulum (ER) plays a role in protein synthesis and folding, but it is the rough ER specifically that is involved in synthesizing proteins that are then transported to the Golgi apparatus for further processing and packaging. The Golgi apparatus is primarily responsible for packaging and secreting proteins

6. Which of the following numbers is the greatest common factor (GCF) of 12 and 18?

• A. 2
• B. 3
• C. 6
• D. 9

Correct answer: C

Rationale: The GCF is the largest number that is a factor of both 12 and 18. We can factor each number to find common factors: 12 = 2 x 2 x 3 and 18 = 2 x 3 x 3. The greatest common factor that appears in both factorizations is 6 (2 x 3).
